The Catalysis Laboratory works under the direction of Dr. Sulaiman Al-Khattaf

Picture above is of Dr. Al-Khattaf and some students in lab in 2003.



  • Pursue basic/applied research in heterogeneous catalysis.
  • Develop a basic understanding of FCC catalysts
  • Enhance the transfer of innovation in catalyst study from laboratory to the industry.
  • Train and educate students on a continuous basis in the science and art of catalysis research.


  • Modeling of Catalytic Reactions


  • A Riser Simulator: A bench scale unit able to simulate the reaction regime in an up-flow (riser) commercial catalytic reactor. It is suitable for quick and reliable catalyst selection,
    It can be used to study kinetic models under reaction times below 20s. It is an experimental system allowing the study of different reaction systems using “lumping” techniques and catalyst deactivation models. This reactor is bench scale equipment with internal recycle unit invented by  Prof de Lasa from the University of Western Ontario
  • The “Riser Simulator” is a fluidized reactor of the “batch” type with internal recycle. It has two sections: a) Lower section, b) Upper section. There is also an annular spacing between the basket and the internal cavity of the reactor. Rotation of the shaft and impeller promotes a low pressure point in the upper section of the basket. This promotes an upwards gas motion in the central section and a down flow gas circulation in the outer section. As a result, the catalyst is fluidized. Rotation of the shat induces at 7600rpm intense fluidization.  For more information about the Riser Simulator please visit the following sites;

  • GC-MS Gas Chromatograph Units
  • Fixed Bed Reactor





What is a catalyst?
A material that accelerates reaction rate and in the process is cyclically regenerated.


Why is catalysis important?
Catalyst technology is foundational to production of energy, fuels, chemicals, pharmaceuticals, and polymers and to improving the quality of air and water.


What do we do in the Catalysis lab?
Conduct experimental, literature and modeling studies of catalytic reactions.
